Sending data when powered with 5V on RAW doesnt work


#1

Hi !

I try to send a value with BLE to my android phone.
When I power my Blueduino with USB, it works fine.
But when I power the Blueduino on RAW pin with a 5V 1A, it doesn’t send any data, but I can keep pair the Blueduino with my phone.

I guest you didn’t remove the line

while (!Serial) {};

This line will block the sketch if there’s no virtual usb port. Please remove the code and try with 5V power source again

Making a mistake like this is very awkward… Thank you for the indication tho !
